模版总结【长期更新】

对拍程序

linux：

1 #!/bin/bash
2 while true;do
3     ./data > data.in
4     ./wrong < data.in > wrong.out
5     ./right < data.in > right.out
6     diff wrong.out right.out
7     if [ $? -ne 0 ] ; then break ; fi
8 done

windows：

1 @echo off
2 :loop
3 data>data.in
4 right<data.in> right.out
5 wrong<data.in> wrong.out
6 fc right.out wrong.out 
7 if not errorlevel 1 goto loop
8 pause goto loop

还有手动开栈的代码：

     int size = 256 << 20; // 256MB  
     char *p = (char*)malloc(size) + size;  
     __asm__("movl %0, %%esp
" :: "r"(p));
